T ell'fwh'om itgna'g C me V Be ft'known thatl, (icons-n1). license, acitizen-bf the United filt ates, residing at "Cleveland, in the countyof Cuyahoga and Statoi- Ohio, have invented certain new and usefulImprovements. in High-Tension Discharge Apparatus,iof which thetollowing is a specification; This invention relates to electrical ap-1o paratus and particularly to improvements for producing high'tensiondischarges from currents'of relatively low voltage such as 'rnay beobtained. from an ordinary electric lightwall socket. The,invention wasespecially designed for use in connection with therapeuticalinstruments, though 'it Will be understood that it is not intended tolimit its usefulness to this plu'pose.' v 2c The principal object ofthe-invention is'to. provide an efiicient apparatus of the above charactei fmhichiis simple in construction compact in arrangement,-inexpensive to manufacture, and is adapted to be connected to anordinary electric lamp socket.

In order that-the invention may be clearly understood, reference will hehad to thenccomp'anying drawing which diagrammatically illustrates thesame, and the novel fea tures thereof-will be distinctly pointed out inthe appended claim.

Referring to the draiving, 1 and 2 repre sent conductors extending froma. plug 3 which is adapted to be connected to an ordi- 3l5 nary electriclamp socket. The'conductor 1 leads to the energizingcoil 4 of exceedinghigh rcsistancepassing around the iron 'core 5 ot an electromagnet,whichis suiaptcd'to attract the armature 6 carried bya spring 7,

-10 connected with the conductor 2, for automatically making andbreaking the circuit in the ordinary manner. The end 8 of the energizingcoil 4 by means of a wire 9, is connected to the usual adjustablecontact, indicated by 10, which is adapted to normally engage thearmature '6 as shown.

Leading from the end '8 of the energizing coil 4: is a wire 11, whichextends to the primary Winding 12 of a high frequency coil, of very lowresistance. The other end 13 of said primary winding is connected to awire 14:, leading to a suitable condenser 15, preferably of the longfiat type, which condenser is connected to the conductor 2 byfib'ineaiis of a wire desi nated by 1. Said primary winding 12 o? thehigh frequency Specification of Letters retest. I

coil'preferably consists or": a. few turns of heavy wire, and 'to. itsend .18 is connected the secondary winding 17 comprising many turns ofcomparatively fine wire, in order to obtain great intensity of current.The tree end or terminal 18 of thesecondary winding 1 of said highfrequency coil is connected to a therapeutical instrument or othersimilar appliance requiring high tension charges for 85 etl'ectiveoperation. *By having but a single. term nal as 18 leading from thesecondary winding of thehigh frequency coil or con nection'toaninstrument, it has been found in practice that the 'eiiiciency of theinstrument has been greatly increased) When the plug 3 is connected toan ordi nary electric lamp wall socket, current of about 110 volts isdrawn through the coin ductor 1, passes-around the iron core 5 throughtheenergizingcoil'e, thence from its endS through the wire 9, andby thecontta'ct IC TtDLtEWimature 6, which as shown is normally in spacedrelation to theend of The current then passesv so through the spring 7to the conductor 2, thus completing the main circuit. The iron coreoupon being magnetized attracts the armature 6, thereby breaking the maincircuit between 6 and 10. The instant the main g5 circuit isjbroken, thesudden interruption of theflow of the su ply current due to the breakingof the circuit, causes said current to charge the condenser 15 bypassing through the Wire 16,.and' then cease while 99 the main circuitis broken between the armature G and the contact ltlyinstantly, thecondenser begins discharging through the wire 16 and conductor 2,through the spring 7, then across the are between the armature e5 6 andthe adjustable contact 10, by way of the wires 9 and 11 't-o'energizetheprimary winding 12 of the high frequency coil, then back through thewiresliancl 1% to the condenser, which elements" constitute the con-10}; denser discharging circuit. The moment the armature 6 is drawn tothe iron-core 5fand While the main circuit. is still. broken between thearmature 6' and the adjustable contacti 10, the iron core Sbecomes nonmsmagnetic and the spring 7 returns the arinatore to its normal positionin engagement discharge Wiif ing currents e wincing of if; this liigii feguency n creased. by inducing said. curren o the secondary winding 17,A sni me s merit connectezl to rho .i
